Tongling Nonferrous Metals Group Co., Ltd., together with its subsidiaries, engages in the copper smelting, copper ore mining, processing of copper products and other related businesses primarily in the People's Republic of China and has a revenue in excess of US$11.2 billion. They are one of the world's leading copper and zinc smelting groups. The company produces gold concentrates containing silver, copper, sulfur, and other elements; iron concentrates; sulfur fine sand products; single-sulphide, iron ore, and iron pellets; copper cathodes; copper flat wires; oxygen-free copper rods; phosphor copper anodes; precision brass sheets and strips; copper sheets and strip classes; lead frame strip classes; phosphor bronze tins; brass rods; self-adhesive and lubricating cables; and resistant wires. It also offers sulfuric acid, copper sulfate, and nickel sulphate. The company was formerly known as Anhui Tongdu Copper Co., Ltd. and changed its name to Tongling Nonferrous Metals Group Co., Ltd. in September 2007. Tongling Nonferrous Metals Group Co., Ltd. was founded in 1992 and was listed on Shenzhen Stock Exchange in 1996. It is headquartered in Tongling City, China. Tongling Nonferrous Metals Group Co., Ltd. is one of the companies with the most complete industry chain in China. In 2011, the copper contained in the self-produced copper concentrate is 48,500 tons, the copper cathodes produced is 854,400 tons, the sulfuric acid produced is 2,067,000 tons, and the gold produced is 11.15 tons. The core business of Tongling is copper smelting. As of the end of 2011, Tongling has total assets of US$5,117 million, net assets of US$1,814 million, sales revenue of US$11.218 billion and total profits of US$296 million.

Being one of the earliest copper production bases of modern China, Tongling Nonferrous Metals (Group) Co., Ltd. began production in February of 1952. It has now become one of China's key production enterprises and is one of the largest industry groups in Anhui province. Its main businesses include mining, smelting and metals processing with total assets of 10 billion RMB Yuan and annual sales revenues up to 6.7 billion RMB Yuan for 2001. It presently produces around 320 categories of products covering nonferrous metals, raw materials, chemicals, machinery and electronics, constructional materials and engineering, and products for light industry. Some 240,000 tons of copper cathodes, one of its main products, were smelted in 2001. The capacity of its blister copper and copper cathode reached the top ten of the nation.

Modern enterprise systems and large-scale reforms were introduced in the construction of Anqing Copper Mine, one of the major mines of Tongling Non-ferrous Metals (Group) Co., Ltd.

China United Copper Co., Ltd. (CUC) www.cucltd.com

China United Copper Co., Ltd. (CUC) was established on 15 March, 2002 in Beijing, China. CUC is a jointly owned company, and was co-founded by China Minmetals Non-ferrous Co., Ltd. and the five backbone smelters in China: Jiangxi Copper Co., Tongling Non-ferrous Metals (Group) Co., Ltd., Yunnan Copper (Group), Ltd., Daye Non-ferrous Metals Co., Ltd., and Shanxi Zhongtiaoshan Non-ferrous Metals (Group) Co., Ltd. The registered capital is 10 million RMB Yuan.
This is the first time for the Chinese copper industry to organize the six industry-giants into an alliance to deal with non-domestic entities and projects. It marks a new milestone for China's copper industry.
CUC's aim is to unify Chinese copper smelters from separate business units into a strong business alliance for the negotiation and import of copper concentrate. Such a strategic action ensures the partners' common interests, namely creating a harmonized "voice" in negotiations with foreign mine-owners concerning joint exploitation and development of overseas mines. The result is the strategic stabilization of raw material supplies for China's domestic smelters, by obtaining the long-term overseas sources. This is a historical moment for our cooper industry, a turning point from short-term and spot copper purchases toward mid-term/long-term and strategic purchases. In addition, the joint development of new overseas copper mine resources will lead toward the realization of long term security.

News April 23, 2012 - Nautilus Minerals Inc. today announced it has signed a binding heads of agreement with Tongling Nonferrous Metals Group Co. Ltd ("Tongling") for the sale of the product extracted from the Company's Solwara 1 deposit located in the Bismarck Sea, Papua New Guinea ("PNG").  The agreement provides for the purchase by Tongling of 1.1 million tonnes per annum (subject to +/- 20% variation) of Solwara 1 material for a period of three years on a take or pay basis, commencing upon the first delivery of product from Solwara 1, targeted in Q4 2013 in accordance with a notification mechanism and includes an option to agree an extension of the arrangement.  "The quality of this relationship with China's largest importer of copper concentrates provides further evidence that there is considerable interest in the high grade massive sulphides being found by the emerging seafloor resource production industry," said Nautilus CEO Stephen Rogers.  The material will be imported into China by Tongling and then processed through its facilities in the city of Tongling alongside the Yangtze River. After production of a copper concentrate it will be smelted in Tongling's industrial complex. The purchase price to be paid by Tongling will be based on the quality of the copper concentrate produced.  The agreement includes a mechanism for an early payment of 90% of the price upon loading of the export vessel in PNG. Final payment is based on the recovery of copper, gold and silver reporting to the copper concentrate with deductions for capped logistics and processing costs, smelter treatment and refining charges (TC/RCs), allowances for plant fixed capital recoveries and Tongling's tolling fee on concentrator plant processing costs. TC/RCs are based on Asian International benchmarks with a premium payable for the achievement of target metal recoveries.  The price payable for all metals will be set by the London Metal Exchange (LME) for copper and London Bullion Market Association (LBMA) for silver and gold with the initial payment for all metals based on the average of the month preceding the shipment and final payment on a four month Quotational Period.  Further value may be realised through a 50%/50% profit sharing scheme based on incremental by-product revenue realised in China, including gold bearing pyrite. Material from the process can be roasted in China to produce gold and sulphuric acid and the remaining calcine may be sold to cement manufacturers or as iron ore fines. With minimal waste Tongling's process brings significant benefits consistent with Nautilus' commitment to minimise environmental impacts.  The Company will issue a bank guarantee to Tongling in three stages over nine months, which will not exceed approximately US$11.5 million, as a security for 50% of Tongling's concentrator investment costs commencing at the first order of major equipment.  Nautilus CEO Stephen Rogers said the Company was looking forward to working with Tongling to realise the full potential of the high grade material extracted from Solwara 1. "We have now closed the value chain on the project, established our first customer for seafloor massive sulphides and look forward to building a long term relationship with Tongling," he said.  Nautilus is currently progressing the build of equipment, including the Seafloor Production Tools and Production Support Vessel (as those terms are used in the Company's Annual Information Form), for the Solwara 1 Project.

Outotec has been awarded a contract by Tongling Non-Ferrous Metals Group for the design and delivery of a new copper smelter to be built in Jinchang in Anhui province, China. The contract value is approximately EUR 15 million.  Outotec's scope of supply includes licenses for both Outotec® Flash Smelting and Kennecott-Outotec Flash Converting technologies, basic engineering and delivery of proprietary equipment for smelting and converting. Chinese Nanchang Engineering Institute is in charge of local engineering and project implementation.  In the first phase, the new plant will have an annual capacity of 200,000 tonnes of copper. The capacity will be expanded to 400,000 tonnes in the second phase with minor adjustments. The new smelter is scheduled to be started up in mid-2012.  "Environmental sustainability is a very important criterion in China today. Tongling chose Flash Smelting combined with Flash Converting, because it is the cleanest copper process available and offers the lowest investment and operating costs together with the most effective emission control", says Pertti Korhonen, CEO of Outotec.
